Cited reference searching means identifying articles that have cited a particular article.
You have an article that is interesting for some reason, and you want to find newer articles that have cited that article in their bibliographies.
You may do this kind of search to follow a trail of research or to examine research impact.
Web of Science is the gold standard database for cited reference searching. Despite the name, it's a multi-disciplinary database covering literature from the social sciences, natural sciences, arts, and humanities -- not just science.
What other sources should you consider? To complement your Web of Science search, choose additional databases according to the subject of your article and the purpose of your search.
Many publishers' websites also offer cited reference searching. If you find your article on its publisher's website, you may find quick links to other articles by that publisher that have cited your article.
